Evolution just loves a nice pair of oversized canines, especially on mammalian predators. Saber-toothed animals have shown up over and over again – we even have some today – but despite their similarities, not all of these toothy species were using their canines the same way. This episode, we explore the various shapes of functions of saber teeth and the disparate lineages that have sported them.

In the news: The Fossil Keeper’s Treasure, the size of megalodon, and vulture feathers.
